What a winning-bid ratio is — Korea's August figure was 84.7 percent, Seoul's was 97
A winning-bid ratio is the price a property fetched at court auction divided by its appraised value. It is not a discount to market price. Appraisals are typically set six months to a year before the sale date, so a ratio above 100 percent may mean prices rose after the appraisal rather than that bidders overpaid. Three numbers are published together and are routinely mixed up: the winning-bid ratio measures price, the sale rate — how many offered properties actually sold — measures whether buyers turned up at all, and the average number of bidders measures competition on the ones that sold. In the August 2026 report GG Auction published on September 7, nationwide apartment auctions showed 3,614 properties offered, a sale rate of 35.4 percent down 1.9 points, a winning-bid ratio of 84.7 percent down 0.7 points and falling for a third consecutive month, and 5.3 bidders on average, unchanged from July. Seoul's ratio fell 4.0 points to 97.0 percent while Gyeonggi's rose 3.0 points to 89.8 percent, its highest in two years, even as Gyeonggi's sale rate dropped 11.4 points
The three lines
- Definition — winning bid divided by appraised value. The appraisal predates the sale by six months to a year, so it is not a market discount
- Three numbers — the ratio measures price, the sale rate measures turnout, the bidder count measures competition. They can move in opposite directions
- August 2026 — nationwide 84.7 percent (third monthly fall), sale rate 35.4 percent, 5.3 bidders. Seoul 97.0 (−4.0pt), Gyeonggi 89.8 (+3.0pt)
Key questions
- What is a winning-bid ratio
- **Winning bid ÷ appraised value × 100.** The denominator is the **appraisal** assigned to a property entering court auction; the numerator is what it actually sold for. An apartment appraised at 500 million won that sells for 420 million has a ratio of **84 percent**. **The most common misreading is treating this as a discount to market price.** The denominator is not market value — it is the **appraisal**. And appraisals are set not on sale day but around the opening of the auction, typically **six months to a year before** the sale. Two consequences follow. **① A ratio above 100 percent is not strange.** If prices rose after the appraisal, selling above the appraised value is normal. **② The same ratio means different things in different markets.** Ninety percent in a rising market and ninety percent in a falling one imply different real discounts. **A winning-bid ratio measures the gap between a valuation made six months ago and today's price, more than it measures value.** Which is why the indicator reads better through **direction and persistence** than through level — the fact that August's nationwide 84.7 percent was a **third consecutive monthly decline** says more than the number itself.
- Is the sale rate the same thing
- **No — and this is the most common confusion, because the terms sound alike.** Auction statistics usually publish three figures. **① Sale rate = properties sold ÷ properties offered.** How many of the properties put up actually found a buyer. **It measures whether anyone showed up.** **② Winning-bid ratio = winning bid ÷ appraised value.** How much the sold ones fetched. **③ Average number of bidders.** How many people competed for each property that sold — **the density of competition.** **The three can move in opposite directions, and Gyeonggi province did exactly that in August 2026.** | Gyeonggi, August | Value | Change from July | |---|---|---| | Winning-bid ratio | 89.8% | **+3.0pt** | | Sale rate | 37.7% | **−11.4pt** | **Prices rose while the share of properties selling collapsed.** That is not a contradiction. It is what happens when buyers crowd onto a few desirable properties and everything else fails to sell. **Judged on what sold, prices look firm; judged on the market as a whole, transactions have frozen.** Reading the ratio alone would tell you Gyeonggi property had recovered — the opposite of what the data says.
- What did August 2026 look like
- **Weak nationwide, falling in Seoul, split in Gyeonggi.** From the August auction report GG Auction published on **September 7, 2026**. | Region | Winning-bid ratio | Change | Sale rate | Change | Avg. bidders | |---|---|---|---|---|---| | **Nationwide** | **84.7%** | −0.7pt | 35.4% | −1.9pt | 5.3 | | **Seoul** | **97.0%** | **−4.0pt** | 37.1% | −1.2pt | 6.1 | | **Gyeonggi** | **89.8%** | **+3.0pt** | 37.7% | **−11.4pt** | 5.9 | | Incheon | 79.1% | −1.3pt | 32.7% | −7.4pt | 6.0 | Nationwide apartment auctions offered **3,614 properties**, slightly fewer than July, and the **average bidder count held at 5.3**, unchanged. The nationwide ratio of 84.7 percent was a **third consecutive monthly fall**. **Three things to take from it.** ① **Seoul's 4.0-point drop is the month's largest.** Ninety-seven percent is still high, but the direction turned. ② **Gyeonggi's 89.8 percent is the highest since August 2024 (90.2 percent)** — set against a sale rate down 11.4 points in the same month. ③ **Sale rates fell in every region listed.** The share of auctions that conclude is moving before price does, consistent with a market where lending rules and property taxation have compressed buying appetite (「Korea's August 13 property package」·「Korea's comprehensive property tax threshold」).
A ratio above 100 percent does not mean bidders overpaid. The denominator is not the market price — it is an appraisal set six months earlier. That single fact changes how half of Korea's auction coverage reads.
1. What is divided by what
`` Winning-bid ratio = winning bid ÷ appraised value × 100 ``
An apartment appraised at 500 million won selling for 420 million gives 84 percent.
| Common misreading | Reality |
|---|---|
| "It is a discount to market price" | The denominator is an appraisal, not a market price |
| "Above 100 means overpaying" | It can mean prices rose after the appraisal |
| "Lower means a better deal" | It may reflect defects or encumbrances on the property |
The key is the time lag. Appraisals are set around the opening of the auction, typically six months to a year before sale. So the ratio measures "the difference between a valuation made half a year ago and today's price" more than it measures value.
Which is why it reads by direction, not level. The nationwide 84.7 percent in August matters less than the fact that it was a third consecutive monthly decline.
2. Three numbers, three different things
| Indicator | Calculation | What it measures |
|---|---|---|
| Sale rate | Sold ÷ offered | Did anyone show up |
| Winning-bid ratio | Winning bid ÷ appraisal | How much the sold ones fetched |
| Average bidders | Bidders ÷ sold | Density of competition |
They can move in opposite directions. Gyeonggi province did so in August 2026.
| Gyeonggi, August | Value | Change |
|---|---|---|
| Winning-bid ratio | 89.8% | +3.0pt |
| Sale rate | 37.7% | −11.4pt |
Prices rose while the share of properties selling collapsed. Not a contradiction — it is what happens when buyers crowd a few desirable lots and everything else fails to sell. On what sold, prices look firm; on the market as a whole, transactions froze.
Reading only the ratio would tell you Gyeonggi had recovered. The data says the opposite.
3. August 2026
From the August report GG Auction published on September 7, 2026.
| Region | Winning-bid ratio | Change | Sale rate | Change | Avg. bidders |
|---|---|---|---|---|---|
| Nationwide | 84.7% | −0.7pt | 35.4% | −1.9pt | 5.3 |
| Seoul | 97.0% | −4.0pt | 37.1% | −1.2pt | 6.1 |
| Gyeonggi | 89.8% | +3.0pt | 37.7% | −11.4pt | 5.9 |
| Incheon | 79.1% | −1.3pt | 32.7% | −7.4pt | 6.0 |
3,614 properties were offered nationwide, and the average bidder count held at 5.3.
- Seoul's −4.0 points is the month's largest fall. Ninety-seven percent is still high, but the direction turned.
- Gyeonggi's 89.8 percent is the highest since August 2024 (90.2 percent) — against a sale rate down 11.4 points.
- All four regions saw sale rates fall. Turnout moves before price.
4. Why these numbers are moving now
Auction indicators move later than the ordinary sale market, but more sharply. Properties do not reach auction because prices fell; they reach auction months after credit tightened and transactions stopped.
Korea's second half of 2026 fits that condition — lending rules and property taxation have compressed buying appetite (「Korea's August 13 property package」·「Korea's comprehensive property tax threshold」), with further changes to jeonse loan residency requirements already announced (「Jeonse loan residency requirement」). If stock keeps piling up while bidder counts hold flat, the sale rate falls first.
5. What is left and what is unverified
- Sale-rate declines differ by outlet. Gyeonggi at 11.4 points and the capital region at 10.9 appear to use different scopes.
- The GG Auction report was not obtained. Figures come from press coverage.
- The six-month-to-a-year appraisal lag is ordinary practice, with wide case-by-case variation.
- The scope of 3,614 properties differs across outlets. Treated here as apartments.
- The two-year-high claim was not checked against the underlying series.
